The structure styles shown in seismic line QZ2006-40 and the results from balanced section showed that the Qianzhong(Central Guizhou) and its adjacent areas have characteristics of zonation obviously, and 4 structural belts can be recognized as northwest Guizhou, Qianzhong, Majiang-Kaili, and Xuefeng tectonic belt. The main structural style in northwest Guizhou tectonic belt is ejective fold, Qianzhong tectonic belt has characteristics of broad fold, Majiang-Kail tectonic belt has characteristics of trough-like fold, and Xuefeng tectonic belt is mainly composed of folded rocks of Fanjingshan Group, Banxi Group and Nanhuan.
